Show images from an SP list in a Gallery on PC and Mobile

[Anonymous]

Hello everyone,

I'm creating an app with a gallery that shows images from a SharePoint list.
I was using the ThisItem.img function (img is a column in my SP list that contains the image link). This function showed the image correctly on the PC, but when I went to test it on Mobile Phones, I found that on mobile, this function does not show any image.

I wanted to know how to show images from an SP List (it can be either by attachment or by link) in a way that the image is shown both on the PC and on mobile.

PS: Searching the forum, I discovered the function ThisItem.'Attachments', but it seems that this function no longer exists. It doesn't even have anything similar to that on my PowerApps.

Can someone help me?

I've accomplished this in the past with an image control inside a gallery and the image value set to

Gallery2.Selected.Thumbnail.Large

My images were stored in a document library. I then used a "ParentID" column to match the record with what attachment images should be shown.

Gallery Items attribute set to: 

Filter(LIBRARYNAME, ParentID=BrowseGallery1.Selected.ID)

Hi @Anonymous ,

I have done a blog on SharePoint Images in Power Apps and in particular mobile devices need a different approach for Library-stored items.

Happy to help after you have read this.

Thanks for the response!
I saw your blog. In the final part of it, where is the part of showing attachments in the gallery, the function you use is: YourGalleryName.Selected.Attachments

As I said in my post, this "Attachments" function does not exist on my PowerApps. The closest to it is "HasAttachments". So I can't do a

YourGalleryName.Selected.Attachments

not even an

ThisItem.Attachments

How can I use or activate this "Attachments" in the gallerys function on my PowerApps?

@Anonymous ,

Firstly, you need to have Attachments activated in your SharePoint list.

I just re-tested one here and

First(GalleryName.Selected.Attachments).Value

produces an image of the first attachment in the selected item in the Gallery.

So how do I activate attachments on my SP list?
I thought that all SP lists already came with the attachment column active, but in a hidden mode.

Currently, my list column looks like this (my SP list is in Portuguese, so "Anexos" = Attachments):

@Anonymous ,

You have it set up correctly - test from here below

The gallery on the left Items is simply a list with some attachments. The Image control on the right (not in the gallery - just on the screen) is displaying the first attachment from the selected item in the list.

Maybe you need 

First(GalleryName.Selected.Anexos).Value
